MDM Trouble Report for 2015 Dec 10 Telescope: 2.4m Observer(s): stephen Lawrence (Hofstra/Columbia) Instrument: OSMOS (imaging mode) Problem(s) Encountered: At around 3 AM the main power shut off briefly, 1--2 seconds, a few times. I had recalled reading in the MDM manuals before arriving that there were procedures for determining if we were on generator or back-up power, but I didn't recall the specifics and the power interruption killed the Internet, which was my primary link to the MDM manuals. So both I and the observer at the 1.3m had trouble figuring out what to do in the case of the main power having brief interruptions. The paper manuals in the observing rooms are scattered and some pages note that they are out-of-date. I couldn't locate the discussion of the power supply in the main paper manual in the 3-ring binder in the notebook. Conservatively, we both decided to follow the lightning shut down procedure, just in case the power troubles worsened/or we were running on battery backup. The next day, Eric noted that the MDM pages are on the local intranet, and so could still be accessed without internet connectivity, but you need to know the IP address. That fact should be posted in the control room. And perhaps all of the basic emergency/hazard procedures (not just the lightning shutdown) should be printed out in a single red three-ring binder. ------------------------------ Submitted on 2015 Dec 12 [11:52:04]
